ATTACHMENT FOR KEYS.

Application filed April 15, 1913.

To all whom it may concern Be it known that I, ARTHUR M. HEIM- BAUGI-I, a citizen of the United States, residing at Kenmore, in the county of Summit and State of Ohio, have invented a new and useful Attachment for Keys, of which the following is a specification.

The present invention appertains to an attachment for keys, and aims to provide a novel and improved device of that character which may be employed for flexibly attaching a key to the shank of a door knob in order that the key may not become lost by dislodgment from the key hole due to the jarring of the door.

It is also the object of the present invention to provide a device of the nature indicated which may be readily attached to and removed from the shank of a door knob, in order that when the key is removed, the attachment may be released from the shank to serve as a guard or key ring to be carried in the pocket, hand-bag or the like.

It is also within the scope of the invention to provide a device of the character described which shall be simple, light, small, durable and inexpensive in construction, as well as serviceable, convenient and efficient in its use.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure 1 is a perspective view of the device as in use. Fig. 2 is a plan view of the device.

In carrying out the invention, reference being bad in detail to the drawing, there is provided a coiled wire or elastic member 1 having one end attached to a small ring 2, and having its other end'or terminal formed into a hook 3. The coil 1 may be of relatively small diameter and should possess a proper degree of resiliency. To the ring 2,

there is attached one end of a chain or fieX- ible connecting member 4, while the free or other end of the chain or flexible member 4 carries a ring or clamp 5.

In use, the ring 5 is clamped about the shank 6 of the key, so that the device may be carried with the key, the hooked end 3 of the member 1 being normally engaged to the ring 2 so that the member 1 may be employed as a key ring or guard when the key is carried in the pocket, handbag or the like. When the key is positioned in the key hole of the door or door lock, the member 1 may be passed around the shank 7 of the door knob, so as to snugly and compressibly embrace the shank, the hook 3 being engaged to the ring 2 so as to maintain the member 1 in position on the shank. In this manner, should the key become dislodged from the key hole, the same will not drop to the floor, but will be suspended by the chain 4, so that the key may not become lost. The member 1 in embracing the shank of the knob will not interfere with the engagement of the hand with the knob, the member 1 being of such proportions as not to work into the opening in the door into which the shank of the knob passes. VVhen the key is to be removed, the member 1 may be readily opened by disengaging the hooked end 3 from the ring 2, as will be apparent. It is also evident that the present device may be employed in connection with various keys and door knobs or other parts adjoining the key holes.

Having thus described the invention, what is claimed as new is In a device of the character described, a ring, a coiled wire spring attached at one end to the ring and having a hook at the other end to engage the ring, the spring being adapted to embrace the shank of a door knob, and a flexible member attached at one end to the ring and having means at its other end for engagement to the shank of a key.

In testimony that I claim the foregoing as my own, I have hereto afiiXed my signa ture in the presence of two witnesses.

ARTHUR M. HEIMBAUGH.
